ACT Aerospace

What ACT Aerospace does

ACT Aerospace (legal entity Applied Composite Technology Aerospace, LLC) is a vertically integrated aerospace and defense manufacturer specializing in autoclave-cured advanced composite structures. Founded in 1985 by Roland J. Christensen in Fayette, Utah, the company relocated to a 350,000+ ft² campus in Gunnison, Utah, including 104,000 ft² of dedicated aerospace manufacturing space and 50,000 ft² pre-staged for new program growth. Core technical capabilities include large-format autoclave curing (current capacity 12' x 40' with a 12' x 50' unit coming online in 2026), 5-axis CNC machining, filament winding, laser ply placement, and in-house Level III Non-Destructive Inspection under NADCAP accreditation for composites, NDI, and measurement & inspection.

The company serves as a Tier 2/3 direct supplier to major aerospace and defense OEMs including Boeing (787 Dreamliner), Sikorsky/Lockheed Martin (military rotorcraft), Bell/Textron (V-280 Valor and other military helicopters), Gulfstream Aerospace (business jets, 2021 Supplier of the Year), Honda Aircraft Company (HondaJet), L3Harris Technologies, and Textron Aviation. ACT provides full lifecycle composite part services spanning part design, tooling design, manufacturing planning, fabrication, testing, and inspection, supported by AS9100D, ISO 9001, ITAR, and NIST 800-171 certifications.

Revenue is generated through negotiated long-term supply contracts on aerospace and defense programs, with hardware sales of custom-manufactured composite components priced via quote-based B2B agreements. The company is privately held and was acquired by The Thermal Group in February 2025, joining Alexander Machine & Tool and George Industries under a diversified manufacturing platform with over a century of combined thermal-management-focused mission-critical manufacturing experience.
